Technology in Practice is a series of short information
pieces on important topics written in an easy understandable What, Why
and How? format. It can be used by ready mixed concrete industry
personnel to support internal as well as customer education.

TIP 3
Aggregate
Sampling for Laboratory Tests  discusses procedures to
ensure that samples obtained for quality control tests are
representative of the stockpiles or other storage locations from
where they are obtained.

TIP 11 
Testing Concrete Cores
- discusses the procedures used for obtaining core specimens for
evaluation of strength of concrete in the structure and the
evaluation of core strength data.

TIP 12  Slump Loss of Concrete discusses the factors that impact the
change in slump of concrete due to temperature and delivery time,
and the factors that can be addressed to control slump loss.

TIP 13 Chloride Limits in Concrete
- addresses the limits on internal chlorides in concrete as
addressed in the Building Code, ACI 318. It discusses reasons for
the limits, sources of internal chlorides, testing for chlorides and
discusses the calculation of chloride content in concrete from the
mixture ingredients.

TIP 14
 Time of Setting of Concrete Mixtures
- this TIP facilitates the understanding of factors impacting
the setting characteristics of concrete and the method to measure it
(ASTM C403).
